To all whom it may concern:

Be it known that l, Smurnn B. BATTEY, a

citizen of the United States, and a resident of the city of New York, (borough oi MenhattenQ in the county and State of New York, have invented it new and Im roved Safety-Razor end Shopping-Device, of which the following is it full, clear, and exact-description.

This invention relates to safety razors and stro ping devices.

' Tile-object of the invention is to produce a stropping device of improved construction which can be reedily manipulated to strop the blade of a safety razor without injuring the edge thereof.

The device. is suhstentielly automatic in its 0 eration with respect to the mechanism 'whio holds the bis 1 reverses i posi- QQ tion on the strep Fun of the blade.

On the peripheral face of the block 1 near the handle 2, a removable. screw 3 is mounted, the purpose of which is to enable the attachment of a. razor strop 4L )rovid ed with a swivel ring 5 through which the screw passes as indicated. This razor strep is applied like a band around the block, and its opposite end is provided with zl slizitlile (5 of elongated. rectangular form, and formed with inwardly projecting gudgeous 7 to which -a locking device 8 ispivotarlly atl plate being slightly hooked sun projec towsrd the lmn lle as shown.

This locking device 8 consists of s the block, the outer end of the said hook w -d arm 16; the outer yond the periphery of the block as imlicated. in this head there rotatebly mounted a reduced shank of a roller 19, which roller extends transversely across the face of the strop, as will he readily understood. The shank 13 projects beyond the head 17 as shown Fig. 3, and carries rigidly a pinion 20. This pinion is in mesh with a segment :21 which is pivotally mounted on a suitable ivot pin 22 at an intermediate point on the -ength oi the arm At a suitable point the segment 21 is formed with an outwardly projecting pin :23 which constitutes a handle for operating the device in a manner which will appear more fully hereinafter.

Referring now especially to Figs. 4 to 7: The roller 19 is provided with a longitudin ally disposed groove 2-1 in the side thereof". This groove extcndsto the end of the roller remote from the shank 18; it internally en lsrged or undercut so as to present the cross section shown in Fig. i. in this way it may be considered as being formed with e rudimentary bore 25 having a reduced slot formed in the side thereof opening out upon the side face the roller. 1

In order ,to hold the razor blade 26 in the roller, 1 provide a blade holder 27, the form of which is clearly shown in Fig. 6. This blade holder consists. .of two oppositely disposed slightly diverging wings 28, of substantially rectangular form, which are integrally united by a longitudinally disposed sleeve or roll 2? This holder is preferably formed of sheet metal and is sli ditly resilientso that the wings 28 tend to ho d themselves in the relation shown in Fig. 6.

Razor blades of a common type usee i safety razors are usually provided with transverse openings 80, as indicated in Fig. 4. At suitable points to aline with these open- 30, i provide similar openings .31 in one the wings 28, and the opposite wing is provided with small pins 32 which project upwardly and which will project into the open- 31 it the wings are forced together.

in placing the razor blade in the roller, the blade is first introduced into the space be tween the wings 2 with the 82 passing through the openings 80 of tie razor blade. The wings 28 are then pressed clo e. together, and the holder with the attached blade is then slid. longitudinally into the roove 24 from its open end. The form of t 1e groove is such that it will maintain the wings in closed position, so that they clamp the blade securely between them in the manner illustrated in Fig. 4. in order to facilitate the entry of the holder into the groove as suggested, the outer end oi the groove preferably slightly tapered outwardly.

Referring again to Fig. 1, when the razor blade is mounted in the roller as illustrated, mil be e ident that the stropping device is eld. in the hand the handle- 3 block.

forced i that is, having openings.

s'rsnso tates the pinion 20 in the opposite direction,

so that the roller 19 turns over and reverses the position of the blade, bringing the edge thereof on the righthand side of the pin ion instead o1"- on the left. The continued movement of the segment toward the left will. then carry the razor blade around the periphery of the block, maintaining it in constant contact with the strep, will be readily understood. In this way the razor blade may be stroppcd with the greatest facility. The swivel ring 5 facilitates the reversing of the strep, if this is desired.

in order to enable the tension or resistance to the movement of the arm 16 to be adjusted, the pivot bolt ii is provided with a helical spring 33which is disposed under the head of the pin and thrusts against the outer -lace of the arm at the center of the By screwing this pivot bolt 14 inwardly, the pressure of the spring upon the arm is, of course, increased, and the resistance to the movement of the arm becomes greater.

The end of the shank 18 is provided with a reduced threaded tip 34, and a handle 35 is adapted to he screwed upon this tip. On account of ti is arrangement, one is enabled to detach the roller from the arm, whereupon the handle may be attached as indicated in Fig. 5, so that the handle 35, together with the shank 18, constitute a handle for the *azor conveniently held while shaving. The razor blade is then provided with a safety guard 36, the construction of which is clearly shown in Figs. 5 and 7. This guard consists of a continuous strap or band 37 which passes around the blade at theouter of this movement ro-- edge of the holder 27, and is clamped to the holder by means of a small set screw 38, as shown in Fig. 7. This strap 37 is provided with outwardly projecting arms 39 which. are slightly inclined as shown, so that their extremities are offset slightly from l0 edge 40 of the blade, as shown. Between these arms 39 a small pressure roller 41 is pivoted, and this roller is adapted to roll upon the face in advance of the razor blade in shaving. The roller operates to press the flesh in the vicinity of the cutting edge, and prevents the skin from being out.

While I havedescribed the blade holder with openings 31 and pins 32 disposed opposite to them, it should be understood that the openings and pins are used simply to adapt the holder for use with razor blades of the description illustrated in the drawing; Where plain 1'2.

zor blades are employed, there is no necessity for the use of the openings 31 or the pins 32, and the blade is held securely in position simply by the clam ,ing action of the wings on the sides of the b ade.
